B-Line Eye Pen

"A lot of people are scared of liquid eyeliner, it seems, but for me the pencil stuff has always been trickier: It smudges and moves, and it always seems to go on too thick. I like the thinnest little stripe, like something you'd get from an ultra fine line flair pen, and this wonder gives you just that. The key is resting the felty tip on its side against your lash line and just dragging it across in short strokes instead of attempting to draw with the point. If you mess up, no sweat: Clean it up with a Q-tip (and, um, a little spit if you're me). Once you're satified, it'll stay all day—no budging." —Erica
